During the last few years, the frequency of bus accidents has gone up significantly. This has caused much delay and inconvenience for the passengers. There have also been serious accidents in which passengers have been killed. The newspapers have taken interest in the problem, and some of the companies that had more than their share of the bad publicity have registered a reduction in the number of passengers. Much of the problem is technical: Buses are old and in bad condition because of the persistent lack of spare parts. But human factors are also important: Many accidents have been caused by high speed driving on bad roads. You have been hired to help the Nairobi City County to design an intervention strategy. IDENTIFY the core problem; the causes of the problem; the effects of the problem and DRAW a problem tree $(10$ marks$)$
